Problems solved by technology

However, due to the detachable structure of the material mold, after the mold enters the high-temperature furnace, it will be severely deformed due to heat, and there will be obvious gaps between the side plate and the bottom plate of the mold, and the batch materials around the bottom of the mold will be exposed to high temperature due to mold deformation. In the air, the carbon black of the foaming agent is oxidized, combined with the resulting ceramic hardening, until the foaming of the product is completed, the thickness of the product is 20-30mm, and the width reaches nearly 1 / 2 of the height of the product blank. The weight of the porcelain body is about Accounting for 15% of the powder consumption of a single blank, the product quality is reduced by about 30% due to the existence of the porcelain block. When the finished product is processed, the edges and corners of the porcelain must be knocked off first, so the edges and corners of the product are also knocked out a lot , the product quality is seriously damaged
To this end, the size of the mold is increased to ensure that the product has sufficient machining allowance, which will inevitably lead to increased energy consumption and cost, and the company's benefits will be seriously affected.
[0003] To sum up: the original foam glass production technology can not completely eliminate the problem of vitrification, there is a large loss of powder, low product yield, high energy consumption, high processing costs, and low utilization of raw materials

Embodiment 1

[0020] Embodiment 1, rectangular mold box is to make with 3mm heat-resistant stainless steel plate. Bottom plate (1) 700 * 540mm, four sides roll up 20mm high enclosure, side plate (2) high 150mm, volume after side plate (2) is assembled in bottom plate (1) is 680 * 500 * 150mm. Weigh the glass batch material and put it into the mold to level it out, then cover it with a 670×490mm cover plate and press it tightly on the glass batch material. Fill all the gaps around the inner cover plate and the gaps around the bottom plate (1) with the pulverized content of 80% anthracite and 20% silica powder mixture, put the mixture of anthracite powder and silica powder on the cover plate, and its particle size is 2mm, silica powder is 85 mesh. It is better to use natural loose filling, so that the fine powder of combustible materials can seal the glass powder in the mold (see figure 1 ).

[0021] Put the fully closed batch material mold into the furnace for preheating. At this time, th...

Embodiment 2

[0022] Example 2, the glass batch material is weighed and put into the mold for leveling, and then the cover plate is pressed. Fill all the gaps in the inner cover plate and the gaps around the base plate (1) with a pulverized content of 70% anthracite powder, 15% wood husk, 10% silicon powder, and 5% wood shavings, and spread a layer on the cover plate Layer anthracite powder, log tree, silica powder, wood shavings mixture, the particle size is 3mm, and the silica powder is 90 mesh.

[0023] When the mold box enters the foaming furnace, the combustible mixture burns from the outside to the inside, and the glass batch is isolated from the high-temperature oxygen-containing air at 480-700°C in the furnace during the preheating stage. With the help of the original heating element, the combustible mixture burns. When the combustible mixture on the mold box loses its sealing effect, the glass batch material begins to melt and forms a film on the surface to form a self-sealing. At ...

Embodiment 3

[0024] Example 3, the mold box is sealed with 80% anthracite powder, 10% log tree, and 10% shaving granular combustible mixture, and combustible materials are put on the cover plate. When the mold box enters the furnace, the combustible mixture burns, which speeds up the rise of the furnace temperature, and at the same time makes the furnace lack of oxygen to further ensure that the glass batch materials are not oxidized, and also realize the sintering of foam glass powder without porcelain. At the same time, the loss of heat-resistant molds and steel frames is greatly reduced in a non-oxidizing environment, which can prolong their service life.

Abstract

The present invention discloses one kind of no-ceramized foamed glass sintering stuffing and its producing process, and the said stuffing is dried solid flammable material. Compounded glass material inside mold box is sealed completely with flammable material, and flammable material is also thrown onto the cover. After the compounded material is set inside furnace, the flammable material burns to raise the temperature inside the furnace and makes the inside of the furnace lacking of oxygen to ensure no oxidation of the compounded material and realize the no ceramization of glass. The present invention solves the technological problem of making glass product no ceramization, raises the quality and yield of glass product, saves material and prolongs the service life of mold and steel frame.

Description

technical field [0001] The invention relates to a foam glass sintering and non-ceramicization process technology. technical background [0002] The existing foam glass sintering technology uses carbon black with a low oxidation temperature as a foaming agent. The oxidation temperature of this carbon black is about 450°C. The black is oxidized and porcelainized, (ceramicization - a layer of glaze-like glassy substance is produced on the surface of the foam glass product, the thickness can reach 40mm, so that the product cannot be fully developed, and the predetermined processing size and capacity cannot be reached. The foaming agent carbon black in the material is oxidized prematurely before sintering, and the batch material loses its foaming function, and forms a white porcelain hardened solid glass block after sintering.) The heat-resistant steel plate is covered on the material powder to make the matching The material is isolated from air during preheating and sintering. ...
