Abstract
A kind of PTC ceramic semiconductors annealing trunnel kiln for Corhart Zac-block, it is that PTC ceramic semiconductors heater element is installed on the inwall of tunnel cave, at the bottom of the kiln of tunnel cave, be provided with track, above track, park kiln car, the sand mold mould that injects fused solution is equipped with in kiln car the inside, kiln car bottom is provided with wheel, kiln car relies on wheel to walk in orbit, the quick heating when work of PTC ceramic semiconductors heater element, in two seconds, can be raised to 250 degree, and power saving, the thermal efficiency reaches more than 90%, the high temperature of tunnel cave the inside makes the sand mold mould that injects fused solution continue to maintain high temperature, can be not cooling immediately, thereby protection Corhart Zac-block can be because of sharply not cooling and damage, improve the qualification rate of product.
Description
Affiliated technical field
The utility model relates to a kind of Corhart Zac-block PTC ceramic semiconductors annealing trunnel kiln.
Background technology
At present, in Corhart Zac-block production process, after batch fused solution is injected to sand mold mould, because fused solution temperature is very high, if cooling immediately, can make Corhart Zac-block occur crackle, cause product rejection to use.
Summary of the invention
For overcoming in existing situation, in Corhart Zac-block production process, after batch fused solution is injected to sand mold mould, because fused solution temperature is very high, if cooling immediately, can make Corhart Zac-block occur crackle, the deficiency that causes product rejection to use, the utility model provides a kind of Corhart Zac-block PTC ceramic semiconductors annealing trunnel kiln, and it can make the fused solution Slow cooling of high temperature, improves the qualification rate of product.
The utility model solves the technical scheme that its technical problem adopts: build on the ground a tunnel cave, PTC ceramic semiconductors heater element is installed on the inwall of tunnel cave, the two ends of tunnel cave are provided with wicket, at the bottom of the kiln of tunnel cave, be provided with track, above track, park kiln car, the sand mold mould that injects fused solution is equipped with in kiln car the inside, kiln car bottom is provided with wheel, kiln car relies on wheel to walk in orbit, before work, first power connection, PTC ceramic semiconductors heater element is started working, quick heating when this PTC ceramic semiconductors heater element work, in two seconds, can be raised to 250 degree, and power saving, the thermal efficiency reaches more than 90%, when the sand mold mould that injects fused solution is put into after kiln car, kiln car is advanced to tunnel cave the inside, the high temperature of tunnel cave the inside makes the sand mold mould that injects fused solution continue to maintain high temperature, can be not cooling immediately, because the temperature of PTC ceramic semiconductors heater element can be controlled at any time, therefore can make the temperature of the temperature of tunnel cave the inside and the sand mold mould of injection fused solution reduce gradually, thereby protection Corhart Zac-block can be because of sharply not cooling and damage, improve the qualification rate of product.
The beneficial effects of the utility model are that protection Corhart Zac-block can not damage because of the temperature difference, improves the qualification rate of product.
