Abstract

The utility model relates to a mould for producing electrically fused brick can effectively solve extension glass kiln pool wall life's problem, and the technical scheme of its solution is, including the sand mould, the sand mould is upper portion open -ended hollow structure, and the inner chamber of sand mould constitutes electrically fused brick's casting space, and the casting space is the step form that the different cube of two width links to each other and constitutes, and the step corner of the boundary of two cubes is provided with the breach of square, and the breach intussuseption is filled with the chamfer inner core, the utility model discloses novel structure is unique, and is simple reasonable, and easy production is with low costs, founding AZS electric smelting tuckstone casting back chamfer straight forming, and work efficiency is high, convenient to use, effectual, economic benefits is showing.

Description

A kind of mould for the production of fused cast refractories

Technical field

The utility model relates to the mould for the production of fused cast refractories, particularly a kind of mould for the production of tuckstone (in step-like and there is arc angling at step place).

Background technology

Fusion casting azs electric smelting tuckstone is with fillet or right angle, and drawing requirement is fine finishining.Tuckstone is when processing and fabricating, during the fillet of mill tuckstone, difficulty is very large, efficiency is very low, and every platform lathe refines fillet every day or right angle quantity is about 30, labour cost every day about 150 yuan, each about 8000 yuan of emery wheel price, more than 18 degree per hour of power consumption.Affect the processing progress of contract, and then affect delivery date, how could produce this tuckstone is fast the problem that those skilled in the art are concerned about.

Summary of the invention

For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of glass furnace founding pool wall structure, effectively can solve the problem extending glass furnace pool wall service life.

The technical scheme that the utility model solves is, a kind of mould for the production of fused cast refractories, comprise sand mold, sand mold is the hollow structure of upper opening, the inner chamber of sand mold forms the casting space of fused cast refractories, casting space be the different cube of two width be connected and form step-like, the step corner of two cubical boundaries is provided with foursquare breach, is filled with chamfering inner core in breach.

The utility model novel structure is unique, and advantages of simple, easily produces, and cost is low, and chamfering straight forming after the casting of fusion casting azs electric smelting tuckstone, operating efficiency is high, easy to use, effective, remarkable in economical benefits.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Provided by Fig. 1-6, the utility model comprises sand mold, sand mold 1 is the hollow structure of upper opening, the inner chamber of sand mold 1 forms the casting space 4 of fused cast refractories, casting space be two width different cube 4a, 4b be connected and form step-like, the step corner of two cubical boundaries is provided with foursquare breach 3, is filled with chamfering inner core 2 in breach 3.

For ensureing result of use, described chamfering inner core 2 is the cross sections of being made up of white fused alumina is fan-shaped strip, and two fan-shaped straight flange places are close in two right-angle surface of plane and breach 3, and outer end is all higher than the outer end of two right-angle surface;

Described chamfering inner core 2 liang of straight flange places exceed two right-angle surface outer ends of breach 3 length d in plane outer end is 2mm; Described chamfering inner core 2 length is equal with the height of casting space 4; Each face of the blank brick of having cast needs to reserve allowance, namely put chi, the size of square chi is generally 2mm, therefore the utility model cast after blank brick, add and only need man-hour the allowance of the 2mm exceeded to polish, just in time form arc angling, do not need extra processing, time saving and energy saving;

In industry, all casting mold main materials are silica sands, the fusing point of silicon is about 1700 DEG C, the cast temperature of fusion casting azs goods is about 1800 DEG C, the pyrosol of casting can be bonded on goods siliceous material fusing, and chamfering position heat is larger, and high-temperature time is longer, causing the bonding siliceous melted material in goods inner corner trim place, is the key link increasing difficulty of processing.The material of chamfering inner core of the present utility model is white fused alumina material, just avoids above phenomenon, and white fused alumina material fusing point is up to more than 2,000 degree, and founding solution can not cause high temperature melting to white fused alumina, not adhesive product inner corner trim place.Therefore inner corner trim place material improves use white fused alumina material, when casting mold makes in order to avoid chamfering is not round and smooth, have the bad phenomenons such as bubble, reserve breach when sand mold makes, then chamfering inner core is stained with separately, compared with prior art, the utility model has the following advantages:

1, brick body outlet aft-loaded airfoil efficiency significantly improves: owing to removing the procedure of proaching talent together from, and the procedure digging chamfering accounts for 1/3rd of the full brick processing used time, and namely working (machining) efficiency improves 1/3rd in tuckstone;

2, chamfer machining power consumption about 10 degree electricity, the tuckstone of a general contract band chamfering is not less than 100, i.e. contract power saving 1000 degree, an emery wheel about about 8000 yuan of proaching talent, this is again a saving, greatly reduces labor strength simultaneously, has good Social and economic benef@.
