Description

It is a kind of using waste and old hot-blast stove ball and introduce recycling stopper production aluminium carbon packet along material Method
Technical field
The invention belongs to fire resisting material fields, are related to the recycling process for subsequent treatment of waste material, and in particular to a kind of using useless Old hot-blast stove ball simultaneously introduces recycling stopper production aluminium carbon packet along the method for material.
Background technique
Currently, stopper turning material is mainly the discarded turning material of generation during stopper Vehicle Processing, the main use of stopper Way is smelting iron and steel continuous casting production flow control, and material is mainly corundum spinel.Hot-blast stove ball is mainly derived from blast-furnace hot-air Furnace overhaul generates, used hot-blast stove ball replaced old hot-blast stove ball, hot-blast stove ball master when being mainly blast furnace overhaul It is used for blast funnace hot blast stove accumulation of heat.Aluminium carbon packet is widely used in the ladle of smelting molten steel, the packet edge of ladle along material, for sealing It with lining refractories in fixed packet body, is washed away vulnerable to molten steel and slag corrosion, mainly uses alumine, flint clay for a long time Deng production, self drainage and slag-resistant erosion are bad, cause this kind of aluminium carbon packet short along material service life, at high cost.Existing steel mill produces Raw stopper turning material, waste and old hot-blast stove ball are all used as industrial refuse to handle, and result in waste of resources and environmental pollution.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, waste recovery recycling is economized on resources, energy conservation and environmental protection, this Invention provide it is a kind of using waste and old hot-blast stove ball and introduce recycling stopper production high-performance aluminum carbon packet along material method.
The technical solution adopted by the invention is as follows: a kind of use waste and old hot-blast stove ball and introduce recycling stopper production aluminium carbon packet Along the method for material, specifically includes the following steps:
Step (1) by the waste and old hot-blast stove ball of recycling, is manually sorted first, surface irregularities is rejected, successively through jaw crushing Machine, cone crushing remove iron in shattering process, then sieve after raymond grinding powder, obtain granularity be 5-8 mm, 8-15mm, The waste and old hot-blast stove ball of 200 purposes, it is spare；
The stopper turning material of recycling is eliminated the false particle between aggregate using rolling processing by step (2), is sieved by second level sieve Point, the stopper turning material of partial size 0.1-1mm is obtained, grain class distribution is that 0.5-1mm accounts for 50-60%, and≤0.5mm is 40-50%；
Step (3) premix powders: by stopper turning material, silicon carbide, the aluminium oxide Ultramicro-powder, silicon ash of the 0.1-1mm processed It is added according to the ratio, is premixed 15-20min in advance, so that powder sufficiently wraps up stopper turning material, pre- mixed powder pack is standby With；
It very counts, matches as follows by weight:
Waste and old stopper 0.1-1mm 40-45%
200 mesh 15-20% of silicon carbide
5 μ 25-30% of aluminium oxide Ultramicro-powder
Silicon ash 10-20%
Step (4) according to the ratio by hot-blast stove ball aggregate, alumine aggregate, hot-blast stove ball powder, aquamaine mountain flour, be added blender, After 1-2 minutes dry-mixed, the mixed powder that step (3) are produced is added, stirs 3-5 minutes, it is resistance to that 446# is gradually added in whipping process Hot stainless steel fibre, is packed into batch can after mixing evenly；
It very counts, is added according to the ratio by weight:
The waste and old hot-blast stove ball 15-20% of 8-15mm
The waste and old hot-blast stove ball 20-30% of 5-8mm
1-5mm alumine aggregate 10-15%
200 mesh aquamaine mountain flour 5-10%
The waste and old hot-blast stove ball 5-10% of 200 mesh
The mixed powder 20-25% of step (3) production
CA-71 cement 3-5%
It is additional that the sodium tripolyphosphate for accounting for gross mass 0.2% is added；0.1% organic fiber；0.8% 446# heat-resistant stainless steel fiber.
The ingredient of the recycling stopper turning material, by mass percentage are as follows: Al2O3, 65-70%, C, 20-25%, surplus are MgO。
The waste and old hot-blast stove ball ingredient is by mass percentage are as follows: Al2O3, 65-70%, surplus SiO2。
The waste and old hot-blast stove ball of recycling, stopper turning material every batch of progress inspection, meet the standard of using in step (1), (2) It is required that according to the proportion of physical and chemical index deciding step (3) and step (4) product.
In step (2), when rolling, the bottom plate and muller of the edge runner used is corrugateds.
In step (3), carborundum powder is 92 carborundum powders.
In step (3), (4), material error of the additional amount greater than 100kg is not more than 1%, the material of additional amount 50-100kg Error is not more than 0.5%, and additional amount < 50kg material error is not more than 0.05%.
Cement is CA-71 cement.
The present invention is using waste and old hot-blast stove ball and introduces recycling stopper production aluminium carbon packet along material for ladle, iron packet edge.
Compared with the prior art, the advantages of the present invention are as follows:
1. the present invention is by recycling waste and old hot-blast stove ball and introducing stopper turning material waste material and aluminium oxide Ultramicro-powder ultra-low cement knot Collaboration system, and the aluminium carbon packet edge material of the preparations such as kyanite, sodium tripolyphosphate, organic fiber, 446# heat-resistant stainless steel fiber is added, Al2O3%, 60-70%, SiO2%, 20-25%, C%, 2-5%, bulk density 2.0-2.5g/cm3, cold crushing strength 30- 40Mpa, the aluminium carbon packet produced using method of the invention are optimized the high temperature performance index of product along material, efficiently solved The problems such as product strength is low, and erosion resistibility is poor.Ladle, ladle packet edge for smelting molten steel, for sealing and fixing packet Internal lining refractories, resistance to molten steel is washed away and slag corrosion, and slag-resistant corrodes and performance of flushing is better than similar product, realizes useless The cycling and reutilization of refractory material hot-blast stove ball and stopper turning material is abandoned, realizing turns waste into wealth, energy saving, energy conservation and environmental protection, Remarkable in economical benefits.
