the rimming action is limited by an early capping operation.Capping may be carried out mechanically by using a heavy metal cap on a bottle-top mold or it may be carried out chemically by an addition of aluminum or ferrosilicon to the top of the molten steel in an open-top mold.3.1.2exclusive —when used in relation to ranges,as for ranges of thicknesses in the tables of permissible variations in dimensions,the term is intended to exclude only the greater value of the range.Thus,a range from 60to 72in.[1500to 18mm]exclusive includes 60in.[1500mm],but does not include 72in.[1800mm].3.1.3heat treatment terms —see 3.1.7,3.1.11,and Termi-nology A 941.3.1.4hot forming —a forming operation producing perma-nent deformation,performed after the plate has been heated to the temperature required to produce grain refinement.3.1.5killed steel —steel deoxidized,either by addition of strong deoxidizing agents or by vacuum treatment,to reduce the oxygen content to such a level that no reaction occurs between carbon and oxygen during solidification.3.1.6manufacturer (material manufacturer)—an organiza-tion that performs or directly controls one or more operations,such as melting,rolling,coiling,and heat treating,that affect the chemical composition or mechanical properties of the material.3.1.7normalizing —a heat treating process in which a steel plate is reheated to a uniform temperature above the upper critical temperature and then cooled in air to below the transformation range.3.1.8plate-as-rolled —when used in relation to the location and number of tests,the term refers to the unit plate rolled from a slab or directly from an ingot.It does not refer to the condition of the plate.3.1.9plate identifier —the alpha,numeric,or alphanumeric designation used to identify the plate.3.1.10plates —flat hot-rolled steel,ordered to thickness or weight and typically to width and length,commonly available by size as follows:Width,in.[mm]Thickness,in.[mm]Over 8[200]Over 48[1200]over 0.229[6.0mm and over]over 0.179[4.6mm and over]3.1.10.1Discussion —Steel products are available in various thickness,width,and length combinations depending upon equipment and processing capabilities of various manufactur-ers and processors.Historic limitations of a product based upon dimensions (thickness,width,and length)do not take into account current production and processing capabilities.To qualify any product to a particular product specification re-quires all appropriate and necessary tests be performed and that the results meet the limits prescribed in that product specifi-cation.If the necessary tests required by a product specification can not be conducted,the product can not be qualified to that specification.This general requirements standard contains permitted variation for the commonly available sizes.Permit-ted variation for other sizes are subject to agreement between the customer and the manufacturer or processor,whichever is applicable.3.1.11precipitation heat treatment —a subcritical tempera-ture thermal treatment performed to cause precipitation of submicroscopic constituents,etc.,to result in enhancement of some desirable property.3.1.12processor —an organization that performs opera-tions,such as decoiling,cutting to length,marking,inspecting,examining,and testing.7Annual Book of ASTM Standards,V ol

refined by secondary processes,including but not restricted to:vacuum-secondary processes,including but not restricted to:vacuum-arc remelt (V AR),electroslag remelt(ESR),and ladle treatment.5.2The steel may be cast in ingots or may be strand cast.5.2.1Strand Cast Slabs:5.2.1.1When heats of the same nominal chemical compo-sition are consecutively strand cast at one time,the heat number assigned to the cast product(slab)may remain unchanged until all of the steel in the slab is from the following heat.5.2.1.2When two consecutively strand cast heats have different nominal chemical composition ranges,the manufac-turer shall remove the transition material by any established procedure that positively separates the grades.5.3The ratio of reduction of thickness from a strand-cast slab to plate shall be at least3.0:1,except that reduction ratios as low as2.0:1are permitted if all of the following limitations are met:.5.3.1The purchaser agrees to the use of such reduction ratios.5.3.2The

continu-ous scanning over100%of the plate surface.5.3.8The plates are through thickness tension tested in accordance with Specification A770/A770M.5.4Plates are produced in either discrete cut lengths offlat product or from coils.5.4.1Plates produced from coil means plates that have been leveled orflattened and cut to length from a coiled product and that are furnished without heat treatment.For the purposes of this paragraph,stress relieving is not considered to be a heat treatment.5.4.2Plates that are annealed,normalized,normalized-and-tempered,or quenched-and-tempered after decoiling shall be considered to be discrete cut lengths offlat products.5.5When plates are produced from coils:5.5.1The manufacturer directly controls one or more of the operations(that is,melting,rolling,coiling,etc.)that affect the chemical composition or the mechanical properties,or both,of the material.5.5.2The processor decoils,cuts to length,and marks; performs and certifies

The purchaser may specify the heat treatment to be used provided it is not in conflict with the requirements of the material specification.6.4When normalizing is to be performed by the fabricator, it may be accomplished by heating uniformly for hot forming. The temperature to which the plates are heated for hot forming shall not significantly exceed the normalizing temperature. 6.5When no heat treatment is required,the manufacturer or processor may opt to heat treat the plates by normalizing,stress relieving,or normalizing and then stress relieving to meet the material specification.6.6If approved by the purchaser,cooling rates faster than those obtained by cooling in air are permissible to achieve specified mechanical properties,provided the plates are subse-quently tempered in the temperature range from1100to 1300°F[595to705°C].7.Chemical

2023年压力容器板行业市场规模分析压力容器是指按照工业标准制造的用于存贮气体或液体的容器。

压力容器板作为压力容器的主要材料之一，被广泛应用于石油、化工、冶金、造船、核工业、医药、食品等行业。

近年来，我国化工、能源等基础产业的不断发展，以及对新能源的需求增加，也给压力容器板行业带来了更多机遇。

一、市场规模目前，我国压力容器板行业的市场规模不断增长。

根据工信部《2019年钢材行业发展报告》，2019年，国内压力容器用钢销售量达到614万吨，同比增长3.7%。

而在2020年新冠疫情对国内经济造成影响严重的情况下，我国压力容器板行业依然保持了一定的增长，预计2020年销售量将达到635万吨左右。

同时，随着安全生产的要求不断提高，压力容器板在市场上的需求也在逐年增加。

未来，随着我国经济的发展以及特种钢材的逐步普及，压力容器板行业市场规模还有望继续扩大。

二、行业结构作为压力容器板的主要生产企业，国内企业主要分布在沿海地区和南方地区，其中龙头企业包括宝钢、武钢、鞍钢、江苏沙钢等。

这些企业在技术和设备方面都具有相当的优势，能够满足市场的需求，提高产品质量和技术含量。

此外，国外压力容器板生产商在国内市场占有一定的市场份额。

因为外资企业具有较强的技术实力和先进的设备，同时对于新产品的研发和开发也更具优势。

不过，在国内市场上，外资企业仍需要面对一些政策和市场方面的限制。

三、发展趋势1. 标准化程度提高随着国家对压力容器行业的不断规范化和标准化，压力容器板行业在技术和设备方面也将得到进一步发展。

未来，压力容器板行业将逐步实现产品标准化，使产品质量和技术含量得到大幅提高。

2. 精细化生产随着科技的不断进步和自动化技术的发展，压力容器板制造业将得到更多的自动化设备和智能化制造技术的支持。

未来，压力容器板行业将逐步实现精细化生产，从而提高产品的生产效率和质量。

3. 绿色环保压力容器板制造业在生产过程中会产生大量的废气、废水等环境污染，随着绿色环保理念的不断深入，压力容器板行业也注重环保产业，逐步推行绿色生产模式和环保技术措施，以减少对环境造成的影响。
