球墨鑄鐵井蓋是很常見的鑄鐵工藝產物。下面我們就來給大家講一下關于影響球墨鑄鐵井蓋的因素。
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、工藝操縱
1、 Process manipulation
要制定工藝操縱規程，提高工人的技能水平，使工藝流程得到準確實行。制造生產中，要對鑄件的質量進行控制與查驗。我們要從原質料推測每種具體產品的控制和查驗的工藝守則與技能條件。
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.
對每道工序都嚴格按工藝守則和技能條件進行控制和查驗。末了對制品鑄件作質量查驗。要配備公道的檢測要領和合格的檢測員。
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、合格的鑄造工藝。
2、 Qualified casting process.
即憑據鑄鐵件布局，對重量和尺寸要詳細，鑄造合金特性和生產條件，選擇合格的分型面和造型、造芯要領，設置鑄造筋、冷鐵、冒口和澆注體系等。以確保獲得更好的鑄鐵件。
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、鑄造用原質料的質量。
3、 Quality of raw materials for casting.
金屬爐料、耐火質料、燃料、熔劑、變質劑以及鑄造砂、型砂粘結劑、涂料等質料的質量、尺度，會使鑄鐵件產負氣孔、針孔、夾渣、粘砂等缺陷，影響鑄鐵件表面質量和內部質量，嚴重時會使鑄鐵件報廢。
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、鑄鐵件的計劃工藝性。
4、 Planned manufacturability of iron castings.
執行計劃時，除了要憑據事實條件和金屬質料性能來確定鑄鐵件什么形狀、尺寸巨細外，還一定要從鑄造合金和鑄造工藝特性的角度來思量計劃的可行性，即較高的尺寸效應和凝集、緊縮、應力等項目，以制止或淘汰鑄鐵件的偏析、變形、開裂等缺陷的產生。通常對鑄鐵件的表面質量，可用比力樣塊來確定鑄件表面粗糙度；表面的渺小裂紋可用著色法、磁粉法檢查。
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.
