Abstract
The invention discloses a heat preservation reinforcing technique for a large horizontal atmosphere sintering furnace. A liner composed of forged steel is arranged in the horizontal sintering furnace, a CFC technique is used for reinforcing, the sintering temperature is 1860 degrees centigrade, and carbon fiber is used for thermal insulation to enable the external temperature of equipment to be the same with a room temperature. The effective space of the equipment is 1.5 meters in length and 400 to 650 millimeters in diameter. The heat preservation reinforcing technique for the large horizontal atmosphere sintering furnace realizes heat preservation and life span prolonging of a silicon nitride sintering furnace under a high temperature environment and a nitrogen feeding environment. The heat preservation reinforcing technique for the large horizontal atmosphere sintering furnace is suitable for the silicon nitride sintering furnace.
Description
Technical field
What the present invention proposed is a kind of large-size horizontal atmosphere sintering furnace insulation strengthening process that sintering character is improved in firing equipment field.
Background technology
The sintering furnace used at present is vertical structure, and do not have inner bag, so service life is short, intensity is low, therefore can not solve the technical problem of sintering furnace sintered silicon nitride goods completely.
Summary of the invention
In order to improve sintering furnace heat-insulating property and intensity, the present invention proposes a kind of large-size horizontal atmosphere sintering furnace insulation strengthening process.This technique adds Carbon fiber thermal insulation layer by forging and stamping steel structure liner, solves the technical problem of sintering furnace heat-insulating property and intensity.
The scheme that technical solution problem of the present invention adopts is:
At the inner bag that horizontal sintering furnace is formed built with forging and stamping steel, adopt CFC technique to strengthen process, sintering temperature, at 1860 DEG C, utilizes carbon fiber heat insulation, makes device external temperature identical with room temperature.
The equipment useful space, long 1.5 meters, Φ 400mm ~ 650mm.
Good effect, uses the technical barrier of insulation and life under the invention solves the high temperature resistant of silicon nitride sintering furnace and adding nitrogen environment.Be suitable for applying as silicon nitride sintering furnace.
Detailed description of the invention
At the inner bag that horizontal sintering furnace is formed built with forging and stamping steel, adopt CFC technique to strengthen process, sintering temperature, at 1860 DEG C, utilizes carbon fiber heat insulation, makes device external temperature identical with room temperature.
Described sintering furnace is used for silicon nitride sintered product.
Technical requirement: high temperature resistant, high pressure, sinter adding under nitrogen condition, sintering temperature is even, service life of equipment is long.
The equipment useful space, long 1.5 meters, Φ 400mm ~ 650mm.
Feature:
1, equipment consists of integral device and adds demineralized water process+automatically controlled+PLC and control.
2, interval heating point 4 intervals, the temperature difference controls ± 5 DEG C.
3, market is solved to the demand of large-scale silicon nitride goods.
4, the blank of current China to large-scale atmosphere sintering furnace is filled up.
5, this device security is strong, and operability is easy.
6, service life of equipment is long, accords with the demands of the market, and provides safeguard to scientific research and industrial products manufacture upgrading.
7, price is external import like product 1/3, and performance is with external same effect.
