影响球墨铸铁井盖生产工艺的因素有哪些?

来源:http://www.jnwszy.com添加时间:2022-04-14 17:02:00

球墨铸铁井盖是很常见的铸铁工艺产物。下面我们就来给大家讲一下关于影响球墨铸铁井盖的因素。

Nodular cast iron manhole cover is a very common cast iron process product. Now let's talk about the factors affecting the well cover of nodular cast iron.

一、工艺操纵

1、 Process manipulation

要制定工艺操纵规程,提高工人的技能水平,使工艺流程得到准确实行。制造生产中,要对铸件的质量进行控制与查验。我们要从原质料推测每种具体产品的控制和查验的工艺守则与技能条件。

It is necessary to formulate process operation procedures, improve the skill level of workers and accurately implement the process flow. In manufacturing, the quality of castings should be controlled and inspected. We should infer the process rules and skill conditions for the control and inspection of each specific product from the raw materials.

对每道工序都严格按工艺守则和技能条件进行控制和查验。末了对制品铸件作质量查验。要配备公道的检测要领和合格的检测员。

Each process shall be controlled and inspected in strict accordance with the process code and skill conditions. Finally, check the quality of the castings. Fair inspection methods and qualified inspectors shall be provided.

二、合格的铸造工艺。

2、 Qualified casting process.

即凭据铸铁件布局,对重量和尺寸要详细,铸造合金特性和生产条件,选择合格的分型面和造型、造芯要领,设置铸造筋、冷铁、冒口和浇注体系等。以确保获得更好的铸铁件。

That is, according to the layout of iron castings, the weight and size shall be detailed, the casting alloy characteristics and production conditions, the qualified parting surface, modeling and core making essentials shall be selected, and the casting reinforcement, cold iron, riser and pouring system shall be set. To ensure better cast iron.

三、铸造用原质料的质量。

3、 Quality of raw materials for casting.

金属炉料、耐火质料、燃料、熔剂、变质剂以及铸造砂、型砂粘结剂、涂料等质料的质量、尺度,会使铸铁件产负气孔、针孔、夹渣、粘砂等缺陷,影响铸铁件表面质量和内部质量,严重时会使铸铁件报废。

The quality and scale of metal furnace charge, refractory material, fuel, flux, modifier, casting sand, molding sand binder, coating and other materials will cause negative pores, pinholes, slag inclusion, sand sticking and other defects of cast iron castings, affect the surface quality and internal quality of cast iron castings, and scrap cast iron castings in serious cases.

四、铸铁件的计划工艺性。

4、 Planned manufacturability of iron castings.

执行计划时,除了要凭据事实条件和金属质料性能来确定铸铁件什么形状、尺寸巨细外,还一定要从铸造合金和铸造工艺特性的角度来思量计划的可行性,即较高的尺寸效应和凝集、紧缩、应力等项目,以制止或淘汰铸铁件的偏析、变形、开裂等缺陷的产生。通常对铸铁件的表面质量,可用比力样块来确定铸件表面粗糙度;表面的渺小裂纹可用着色法、磁粉法检查。

When implementing the plan, in addition to determining the shape and size of iron castings based on factual conditions and metal material properties, we must also consider the feasibility of the plan from the perspective of casting alloy and casting process characteristics, that is, higher size effect and items such as agglutination, contraction and stress, so as to stop or eliminate the occurrence of segregation, deformation, cracking and other defects of iron castings. Generally, for the surface quality of iron castings, the specific force sample block can be used to determine the surface roughness of castings; Tiny cracks on the surface can be inspected by coloring method and magnetic particle method.
