Pouring technology for castings

Abstract

The invention discloses a pouring technology for castings. The pouring technology is characterized by comprising the steps of 1, preparing; 2, pouring and 3, production safety protecting; in the preparing step, whether casting ladles are dried, whether sprue mouths are smooth and flat, whether slag collection agents are prepared completely, whether slag removing tools are prepared and whether products needing chilling block addition are prepared completely are inspected before pouring everyday; in the pouring step, a first molten iron ladle discharged from a furnace is used for pouring unimportant castings, waste castings replace chilling blocks, the slag collection agents are uniformly scattered over molten iron of each casting ladle, a slag remover removes slag on the sprue mouths, and the height from ladle spouts to sprue cups is generally controlled to be within 150-200 mm; in the production safety protecting step, workers need to wear labor protection appliances before working, need to operate safely and reliably in the ladle pouring process, do not fill the casting ladles with too much molten iron when receiving the molten iron, need to concentrate on the pouring process without glancing at feeder heads, need to move gently with carefulness and discretion when handling weights and shifting boxes and need to clear sites after pouring is completed. The pouring technology has the advantages that the method is simple, a plurality of repeated processes are eliminated, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a casting pouring process. Background technique [0002] At present, the casting casting process is relatively complicated, and there is no unified specification and standard, resulting in uneven quality of the produced castings. Many repeated processes also make the production efficiency low, increase the labor burden of workers, and at the same time make the market competitiveness of the products not tall. For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a casting pouring process, which is simple, eliminates many repetitive processes, and improves work efficiency. [0004] In order to achieve the above object, the...
