Abstract

The invention discloses a deslagging process for automatic casting line production, and aims at providing a simple deslagging process for the automatic casting line production. The technical scheme adopted by the invention is that the deslagging process for the automatic casting line production comprises the following steps of processing slag stopping cotton into a strip, and putting the slag stopping cotton at a casting ladle nozzle of an automatic casting line, wherein the slag stopping cotton is made of alumina silicate fibers. The deslagging process disclosed by the invention is simple and has a good using effect; by adopting the method of putting the slag stopping cotton at the casting ladle nozzle, the slag inclusion flaw rejection rate of castings is effectively reduced, and the finished product ratio of the castings is increased.

Description

A kind of deslagging process cast in transfer matic production

Technical field:

The present invention relates to the production technology of casting transfer matic, particularly a kind of deslagging process cast in transfer matic production.

Background technology:

The feature of present transfer matic Foundry Production, be that rhythm of production is very fast, this just requires that operative employee often repeatedly slag hitting just will can make molten iron clean surface, so not only affects rhythm of production, also can stop over molten iron cast, cause pouring temperature not reach the disadvantages such as technological requirement; And operative employee often has little time slag hitting, production line just starts pouring cast part, and this will cause foundry goods to occur the defects such as slag blister, and percent defective is risen violently, and causes a large amount of cost wastes, has a strong impact on the product quality that casting transfer matic is produced.

Summary of the invention:

The object of this invention is to provide a kind of technique simply cast transfer matic produce in deslagging process.

Technical scheme of the present invention is, a kind of deslagging process cast in transfer matic production, it is characterized in that: pushing off the slag cotton is processed into strip, be placed on the pouring ladle mouth place of casting transfer matic, described pushing off the slag cotton selects alumina silicate fiber felt to make.

Present invention process is simple, and result of use is good, adopts and places pushing off the slag this method cotton at pouring ladle mouth, effectively reduces foundry goods slag blister defect percent defective, improves casting yield.

Detailed description of the invention:

Thin description embodiment,

A kind of deslagging process cast in transfer matic production, pushing off the slag cotton is processed into strip, fixed placement is near the pouring ladle mouth of casting transfer matic, described pushing off the slag cotton selects alumina silicate fiber felt to make, not only can be high temperature resistant, not easily broken, and the surface scum in molten iron is adsorbed, because during cast, pushing off the slag cotton swims in molten iron surface all the time, and its not with the adhesion of bag wall, the effect of pushing off the slag, filter residue, absorption scum silica frost can be served, effectively can reduce the percent defective of foundry goods slag blister like this, improve the yield rate of foundry goods.

Present invention process is simple, and result of use is good, adopts and places pushing off the slag this method cotton at pouring ladle mouth, effectively reduces foundry goods slag blister defect percent defective, improves casting yield.
