Abstract

The invention discloses dry horizontal rotary type smelted steel slag treatment equipment and a heat recovery method, and relates to the technical field of smelting industries, in particular to steelslag treatment, specifically particular to equipment of complete dry treatment and waste heat separation and extraction for 400-series stainless steel slag, AOD (Argon Oxygen Decarburization) smeltingslag, LF refining slag and slag of special steel such as bearing steel and tool steel, and a use method of the equipment. The equipment comprises a supporting structure, a transmission device, a rotary device, end face seals, a slag inlet pipe, an air outlet pipe and a high-temperature industrial monitor, wherein the rotary device is arranged at the upper part of the supporting structure in parallel along a horizontal direction; the transmission device is arranged on the supporting structure and the rotary device; two ends of the rotary device are closed by the end face seals; the slag inletpipe is arranged on the supporting structure; the slag outlet side of the slag inlet pipe is fixed on the end face seal on one side of the rotary device; the air outlet pipe is arranged on the supporting structure, and the air inlet side of the air outlet pipe is fixed on the end face seal at the other end of the rotary device; the high-temperature industrial monitor is mounted on the end face seal. The dry horizontal rotary type smelted steel slag treatment equipment disclosed by the invention solves the problems of flowing of water formed by non-evaporation of cooling water, severe working environment and heavy dust.

Description

technical field [0001] The present invention relates to the technical field of the smelting industry, specifically steel slag treatment, especially the completely dry treatment of 400 series stainless steel slag, AOD smelting slag, LF refining slag and special steel such as bearing steel, tool steel slag, etc. and the separation and extraction of waste heat Equipment and how to use it. Background technique [0002] The currently known treatment methods for 400 series stainless steel slag, AOD smelting slag, LF refining slag and special steel smelting slag are typically "wet method" and "semi-dry method". "Semi-dry method" is divided into "slag pan semi-dry method" and "hot splash semi-dry method". [0003] The "wet" treatment process is divided into four steps: the first step is to put the slag tray (or tank, barrel) containing the molten steel slag in the atmosphere, and wait for the heat to be lost to a certain extent (the slag temperature drops to a certain temperature) ...
