铸铁平板通常采用强度较高的铸铁作为材质，由于铸铁平板用于动力机械设备等的装配，因此铸铁平板磨损速度要比检验平台和划线平台快的多，那么铸铁平板的耐磨性能在一定程度上决定着它的使用寿命。为了使铸铁平板的使用寿命更长久，对装配平板进行时效处理是其生产过程中必不可少的一项。
铸铁平板对精度的要求没有检验平台和划线平台那么高，它主要用于动力机械设备、船舶机械等的装配以及调试工作，一般的铸铁平板表面会带有T型槽，可以用来固定机械设备、机械部件等，方便装配。铸铁平板还可以拼接使用，对于比较大型的机械设备装配，当一块铸铁平板不能独立承担装配工作的时候，就可以将对块铸铁平板拼接起来使用了。
铸铁平板的精度等级遵循一般铸铁平台的精度划分要求，按国家标准计量检定规程执行，分别为0、1、2、3四个等级。规格方面，有大多数铸铁平台的通用规格，如果遇到特殊要求的规格是可以根据图纸或用户的要求进行特别制作的。
铸铁平板的保养方法：
铸铁平板适用于各种检验义务，精密丈量用的基准平面，用于机床机械丈量基准，检查零件的尺寸精度或形位倾向，并作精密划线。在机械制造中也是不可缺少的基本工具。材质：材料为高强度铸铁HT200-250义务面硬度为HB160—210。经过两次处置(野生退火600?----700?和自然时效2---3年，使该产品的精度动摇，耐磨功用好。精度：按国度标准计量检定规程实施，区分为0，1，2，3级四个级别。
铸铁平板的表面质量：规格：200mm×200mm—2000mm×4000mm(特地规格可根据需方图纸制造或单方商定消耗加工)检验标准：用涂色法检验。0级1级平板平台在每边为25mm平方的范畴内不少于25点。2级平板平台在每边为25㎜平方的范畴内不少于20点。3级平板平台在每边为25mm平方的范畴内不少于12点。
铸铁平板表面不应有锈迹、划痕、碰伤及其他影响使用的外观缺陷。表面不应有砂孔、气孔、裂纹、夹渣及缩松等铸造缺陷。各种铸造表面应消除型砂、且表面平整，涂漆坚固。各棱边应修钝。铸铁平台在精度等级低于”00″级的平台义务面上，关于直径小于15mm的砂孔答使用相同的材料堵塞，其硬度应低于周围材料的硬度。在义务面上堵塞的部位应未几于周围，其相互之间的距离应不小于80mm。
为了防止铸铁平板发作有害的变形，在安装铸铁平台平板时，要将支承支在主支点处。支承时，尽量将铸铁平台平板的表面调整到程度面内。为了防止铸铁平台平板发作永世变形，检验结束或划线结束后，要把工件抬下去，不得长时间放在平板上。使用结束，要及时擦净平板的义务面，然后涂上一层防锈油。假设相比长时间不用，最好涂上一层黄油，然后铺一层白纸。最好用木板制造的一个公用罩，不用平板时，用罩子将平板罩住。严禁水滴在铸铁平台平板上，铸铁平台平板要实施周期检定，检定周期要根据使用的具体情况一定，一般为1年。
Causes of Fast Wear Speed of Cast Iron
Plate and Maintenance Method
Cast iron plate is usually made of high
strength cast iron. Because cast iron plate is used for assembling power
machinery and equipment, the wear rate of cast iron plate is much faster than
that of inspection platform and marking platform. The wear resistance of cast
iron plate determines its service life to a certain extent. In order to prolong
the service life of cast iron plate, aging treatment of assembled plate is an
indispensable part of its production process.
Cast iron plate is not as high as
inspection platform and marking platform. It is mainly used for assembling and
debugging of power machinery equipment and marine machinery. Generally, cast
iron plate surface will have T-grooves, which can be used to fix mechanical
equipment and mechanical components for easy assembly. Cast iron plate can also
be used for splicing. For large-scale mechanical equipment assembly, when a
cast iron plate can not undertake the assembly work independently, it can be
used for splicing the cast iron plate together.
The accuracy grade of cast iron plate
follows the accuracy classification requirements of common cast iron platform,
and is implemented according to the national standard metrology verification
rules, which are 0, 1, 2 and 3 grades respectively. In terms of specifications,
most of the general specifications of cast iron platforms can be specially
manufactured according to drawings or user requirements if special requirements
are encountered.
Maintenance method of cast iron plate:
Cast iron plate is suitable for all kinds
of inspection obligations, precise measurement of the reference plane, used for
machine tool mechanical measurement benchmark, check the dimensional accuracy
of parts or shape orientation, and make precise marking. It is also an
indispensable basic tool in mechanical manufacturing. Material: Material is
high strength cast iron HT200-250 duty surface hardness is HB160-210. After two
disposals (wild annealing 600? - - 700? And natural aging 2 - - - 3 years), the
precision of the product is shaken and the wear resistance function is good.
Accuracy: According to the national standard metrology verification rules, it
can be divided into four levels: 0, 1, 2 and 3.
Surface Quality of Cast Iron Plate:
Specification: 200mm *200mm-2000mm *4000mm (Specific specifications can be
manufactured according to the demand side drawings or unilaterally agreed
consumption processing) Inspection Standard: Inspection by coloring method.
Level 0 and Level 1 flat platforms have no less than 25 points in the area of
25 mm square on each side. Level 2 flat platforms have no less than 20 points
in the range of 25_square on each side. Level 3 flat platforms are not less
than 12 points in the 25 mm square area on each side.
There should be no rust marks, scratches,
bruises and other appearance defects on the surface of cast iron plate. There
should be no casting defects such as sand hole, gas hole, crack, slag inclusion
and shrinkage porosity on the surface. All kinds of casting surfaces should be
free of moulding sand, and the surface should be smooth, and the paint should
be firm. The edges should be blunt. On the platform duty surface of the cast
iron platform whose precision grade is lower than "100", the same
material is used to plug the sand holes with diameter less than 15 mm, and the
hardness of the sand holes should be lower than that of the surrounding
materials. The blocked parts on the obligatory surface should be no less than
around, and the distance between them should be no less than 80 mm.
In order to prevent harmful deformation of
cast iron platforms, support should be supported at the main fulcrum when
installing cast iron platforms. When supporting, try to adjust the surface of
the cast iron platform plate to a certain extent. In order to prevent the
permanent deformation of the cast iron platform plate, after the end of
inspection or marking, the workpiece should be lifted down and not put on the
plate for a long time. At the end of use, clean the obligatory surface of the
plate in time, and then coat it with rust-proof oil. Assuming you don't use it
for a long time, it's better to apply a layer of butter and then a layer of
white paper. It's better to use a common cover made of wooden boards. When you
don't need a flat plate, use a cover to cover the flat plate. It is strictly
forbidden to drop water on the cast iron platform plate. The periodic
verification of the cast iron platform plate should be carried out. The
periodic verification should be fixed according to the specific conditions of
use, generally for one year.
