Embodiment Construction

[0021] A brick-making process of deep processing of waste steel slag, including two processes of hot-smelling steel slag treatment and steel slag brick-making. The specific process steps are as follows:

[0022] (1) Incoming slag: the steelmaking workshop pours molten converter steel slag into the slag tank, and the slag tank is transported to the slag-span workshop by a straddle truck;

[0023] (2) Lifting and transporting the slag tank by driving: the crane in the slag crossing workshop lifts the slag containing slag tank and places it in the slag tank tipping machine;

[0024] (3) Slag dumping by the slag tank tipping machine: the slag tank tipping machine transports the slag tank to the predetermined slag dumping area for dumping and dumping. Lift the empty slag tank and return to the steelmaking workshop for slag discharge;

[0025] (4) Roller crusher breaks slag: Roller crusher performs multiple roll crushing to crush steel slag, interspersed with water spray cooling op...

Abstract

The invention relates to a brickmaking technique for deeply processing waste steel slag. The steelmaking slag is subjected to rolling and crushing and pressure-hot stew treatment and the magnetically separated waste steel slag is taken as the main aggregate for making brick. The waste steel slag is used for replacing the lime pebble in the traditional brickmaking technique and is mixed with the river sand and cement for making the brick, wherein the steel slag content is 60%-75%, the river sand content is 10%-15% and the cement content is 15%; the end product of brick is acquired through the processes of forming, laminating, airing, separating and brick stacking. According to the brickmaking technique for deeply processing waste steel slag provided by the invention, the additional value of recycling of the waste steel slag is increased, the solid waste discharging is reduced and the brickmaking technique has the advantages of reasonable technique, high economic benefit and environment-friendly and energy-saving effects.

Description

technical field [0001] The invention relates to the technical field of recycling and utilization of iron and steel smelting waste, in particular to a technology for making bricks through deep processing of waste steel slag. Background technique [0002] Steel slag is the main solid waste in the steelmaking process. The traditional steel slag treatment method is to recover the effective iron element after magnetic separation, and the steel slag tailings are discharged as waste, or used as backfill for general road construction. The existing steel slag recycling method has low utilization rate and small economic benefits, and cannot truly realize the utilization of scrap steel slag from waste to treasure. Contents of the invention [0003] The invention provides a brick-making process through deep processing of waste steel slag to solve the problems of low utilization rate and low economic benefit in the prior art. [0004] The technical solution adopted by the present inve...
