Problems solved by technology

[0008] The common defect of the existing technology is that the process steps are relatively complicated, the production cycle is long, and the steel slag must be cooled first. Since the slag pit system is 8m deep underground, it is inconvenient to maintain and exploit the steel slag after treatment.

Embodiment Construction

[0037] The following examples illustrate the converter steel slag crushing method of the present invention without limitation in conjunction with the accompanying drawings. Those of ordinary skill in the art can also make various changes and modifications to the present invention without departing from the spirit and scope of the present invention, but all equivalent technical solutions belong to the category of the present invention, and the protection of the present invention The scope is defined by the claims of the present application.

[0038] Taking a production line for processing steel slag with an annual output of 6 million tons of steel as an example, a total of 8 slag boxes with a length of 18m, a width of 12m and a height of 3m were built in the hot slag pouring workshop with a length of 180m and a width of 27m. For the three retaining walls of the slag box, cast steel plates are used as protective plates to protect the reinforced concrete retaining walls, and the ...

Abstract

The invention relates to the steel slag recovery and reclamation processing technology. The invention provides a disruption method of converter steel slag, which is characterized in that the steel slag is poured into a dross box in a hot slag splashing workshop under the temperature of 1050 to 1150 DEG C, little water is sprayed to reduce the temperature, after an isolation layer is formed, the slag is poured and water is sprayed continuously time and again, and then the broken steel slag is obtained after warming up stuffily. The steel slag processed through the method of the invention has the advantages of good graining effect and performance, and the method and the process are advanced, the investment on the system is low, the operating cost is low, and the economic effect is obvious.

Description

【Technical field】 [0001] The invention relates to a metallurgical solid waste steel slag treatment technology, in particular to a method for hot stuffing a steel slag slag box. 【Background technique】 [0002] Taking the metallurgical solid waste discharged by iron and steel enterprises as the processing object, the production of new building materials such as new building materials through regeneration and recycling is a circular economic means of today's industrial manufacturing industry. This steel slag product has good performance and low production cost, and is generally welcomed. [0003] The requirements for evaluating steel slag treatment technology are: investment treatment cost, production safety, easy operation, environmental protection, and granulation effect. Among them, environmental protection and granulation effect are being paid more and more attention. Treatment methods that pollute the environment and work in poor conditions are unacceptable. Good granul...
