Description

A kind of foundry goods weld seam antiscuffing paste

Technical field:

The present invention relates to polishing agent technical field, be specifically related to a kind of foundry goods weld seam antiscuffing paste.

Background technology:

Foundry goods is the metal forming object obtained by various casting methods, namely the liquid metal smelted, inject in preprepared casting mold with cast, injection, suction or other casting method, after cooling after the following process means such as polishing, the obtained object with definite shape, size and performance. Owing to cast properties is excellent, in automobile making material, therefore occupy very big proportion, particularly some machining accuracies fundamental parts high, expensive, such as cylinder head, cylinder block, case of transmission etc. Foundry goods is manufacturing and in use procedure, the situations such as crackle, pore, damage is often occurring, it is necessary to carry out soldering. Owing to foundry goods carbon content is high, impurity is many, and have that plasticity is low, weldability is poor, to characteristics such as rate of cooling are sensitive, weld seam easily occurs after soldering. For the surface quality of foundry goods and do not affect it and normally use after improving welding, it is necessary to it is processed by shot blasting. At present, major part polishing is performed by buffing machine, and the direct butt welded seam of grinding tool is polished, it is easy to destroys weld seam, and does not reach user demand.

Summary of the invention:

The technical problem to be solved is in that to provide a kind of foundry goods weld seam antiscuffing paste being favorably improved polishing effect and surface quality of continuous castings.

The technical problem to be solved adopts following technical scheme to realize:
