Abstract
The invention provides a method for producing a cast stone plate and an annealing device thereof. The production method comprises the following steps: (1) adding an auxiliary material to basalt or diabase to prepare a raw material for producing the cast stone plate; and (2) obtaining a product by high-temperature melting, casting molding, crystallization and annealing of the raw material. A roller kiln annealing method is adopted for the annealing in the production steps of the cast stone plate, that is, the products are continuously placed on a roller way in a monolayer manner and move along with rotation of a roller, thus gradually realizing cooling and the annealing. The temperature of a kiln inlet is 650-850 DEG C, and the temperature of the end of the kiln, that is, a product outlet, is below 50 DEG C. The annealing device (the roller kiln) for producing the cast stone plate comprises a kiln body 1 and the roller way 2; the kiln body 1 is internally provided with the roller way 2; and the length of the kiln body is 80-200m and the effective width of the roller way is 0.5-2m according to requirements of different outputs. The method helps solve the problems of long annealing cycle, low yield, low output and high energy consumption in the existing production procedures of the cast stone plate.
Description
Technical field
The invention belongs to a kind of production method and device thereof of building materials, be specifically related to a kind of production method and device thereof of cast stone sheet material.
Background technology
Cast stone sheet material is a kind of infant industry material with excellent wear-resistant antiseptic property, and it has been widely used in making the wear-and corrosion-resistant lining in equipment and the facility in the industries such as coal, electric power, metallurgy, chemical industry, obtains good economic and social benefit.
The production technology of cast stone sheet material is basalt or diabase to be equipped with attach material, is prepared into the raw material that meets cast stone sheet material composition and manufacturing technique requirent, then with raw material through operations such as high temperature melting, moulding by casting, crystallization, annealing and process.Wherein annealing is one of operation particularly crucial in producing, because of its output, energy consumption, cost etc. that directly affect product receive much attention.
Existing cast stone board materials production method for annealing has two kinds: a kind of is that another kind is to anneal with tunnel cave with box kiln annealing.Before a kind of be archetype, but because the small investment of putting up a kiln still has the enterprise's employing more than 50% at present; Build in the ordinary circumstance one linecasting stone slab production line formula of seat-box more than 40 annealing kiln is arranged; Box kiln is a kind of stationary kiln, and because of its shape is also claimed " chicken coop kiln " as chicken coop, majority is to be added to the kiln temperature more than 700 ℃ with coal just piece of cast stone sheet material to be piled in the kiln; Kiln is filled the rear enclosed wicket; Treat then to open wicket when the nature cooling promptly is annealed to normal temperature, the workman gets into and searches product in the kiln, and this kiln annealing cycle generally is no less than 72 hours; A kind of tunnel cave annealing in back has had significant improvement than the former, and general kiln length is more than 80 meter, and more than 50 kiln car circulation arranged; Be mostly the intensification that burns gas, when the kiln car temperature of loading of kiln mouth reaches 700 ℃ for a long time, begin to go in the kiln car one of glass cermaic plate is packaged; Kiln car is filled the back and is moved to the annealed zone, and the back kiln car that preheating is good gets into the loading of kiln mouth thereupon, and this moment continues to heat, be incubated in loading of kiln limit, limit; With this continuous operation that circulates, this kiln product annealing cycle can shorten to 40 hours, the box annealing furnace that all obviously is better than such as low of high, the energy consumption of yield rate; But, also only adopt at present less than 50% enterprise because the investment of construction tunnel cave is higher.As stated, no matter box kiln method for annealing or tunnel cave method for annealing all are product annealing then earlier in heaps,, cause occurring long, problems such as yield rate is low, yield poorly, energy consumption height of annealing cycle so exist the slow and uneven phenomenon of heating and cooling.
Summary of the invention
The present invention will provide a kind of production method and device thereof of cast stone sheet material, promptly with roller kilns annealing solves that the annealing cycle is long in the existing cast stone sheet material production process process, yield rate is low, yields poorly, energy consumption is high problem.
The present invention adopts following technical scheme
A kind of production method of cast stone sheet material may further comprise the steps: 1, basalt or diabase are equipped with and attach material, be prepared into the raw material that is used to produce glass cermaic plate; 2, raw material is processed product through high temperature melting, moulding by casting, crystallization, annealing.The roller kilns method for annealing is adopted in annealing in the production stage of cast stone sheet material, and promptly product is spread in a single layer on roller-way continuously, and moves along with the rotation of roller, progressively realizes cooling annealing.According to the product of different size, the kilneye temperature is 650 ℃-850 ℃, other everywhere temperature formulate according to annealing curve, the end of kiln is that products export place temperature is below 50 ℃.A kind of annealing device of producing glass cermaic plate, promptly roller kilns comprise kiln body 1, roller-way 2, are provided with roller-way 2 in the kiln body 1, according to wanting of different output, confirm the long 80-200m of kiln body, the effective wide 0.5-2m of roller-way.
The present invention compares against existing technologies has following beneficial effect
Anneal because can the annealing cycle be shortened in 4 hours with roller kilns; This has just changed that present glass cermaic plate is placed in the annealing device after several days could kiln discharge; Just can know situations such as yield rate, output, quality, and the problem of the present invention in only in several hours, just can finding to produce, the relevant technological parameter with each of prescription of adjustment product in time is highly advantageous to; So that it is best that output, quality reach, energy consumption, cost are minimum; Because of the roller kilns fuel gas buring is abundant, good seal, so environmental pollution is little; Going out the firer has the fixed position in the workshop, from roller-way, search product in order, thereby make labour intensity low.
