Abstract
Provided is a novel high-temperature salt bath furnace body. Refractory bricks are used as furnace refractory brickwork. A layer of refractory fiber felt is coated outside the refractory brickwork, wherein the refractory fiber felt is aluminum silicate refractory fiber felt. The thickness of the refractory fiber felt is 10 mm to 30 mm. A low-carbon steel iron plate crucible is welded on the outside of the refractory fiber felt. The thickness of the low-carbon steel iron plate crucible is 10 mm to 30 mm. According to the novel high-temperature salt bath furnace body, a steel crucible is not arranged inside the salt bath furnace body, the layer of aluminium silicate refractory fiber felt is coated outside the refractory brickwork and the low-carbon steel iron plate crucible is arranged on the outside of the refractory fiber felt, wherein the thickness of the low-carbon steel iron plate crucible is 10 mm, so that in the thermal treatment heating process, after four corners of the furnace refractory brickwork leak salt, the salt liquid can permeate into the refractory fiber bricks and a solid protection layer is formed. Leakage of fused salt is prevented and the service life of the furnace body is prolonged by more than twice.
Description
Technical field
The present invention relates to the heat treatment technics field, particularly a kind of new type high temperature salt bath furnace body of heater.
Background technology
What traditional salt stove was used is that heat resisting steel or mild steel are made crucible, and four jiaos of place's crackings leak salt below masonry of burner hearth, therefore can not carry out high-temperature heating.
Summary of the invention
Adopt the salt bath of high-quality, do the burner hearth refractory brick marshalling with refractory brick, that heat resisting steel or mild steel are made crucible and traditional salt stove is used, outside four jiaos are surrounded by the aluminosilicate refractory fiber felt outward, then its outside is welded with mild steel iron plate crucible again, guarantee long-time heated parts higher than 1200 ℃ of temperature the time, and be unlikely to four jiaos of place's cracking leakage salt below masonry of burner hearth.
The present invention has overcome traditional middle thermohaline stove (950 ℃), can not carry out the shortcoming of high-temperature heating, traditional salt bath furnace high-temperature heating there are two kinds of methods, a kind of is to add the crucible that a heat resisting steel or mild steel are made in crucible inside, in the process of heating and cooling repeatedly, crucible very easily is out of shape aging and affects the life-span due to salt bath furnace; Another kind is to be provided with the crucible salt bath directly to contact with refractory brick marshalling, and at this moment, make masonry of burner hearth bottom crack leak salt oozes salt owing to expanding with heat and contract with cold, and makes the life-span of salt bath furnace extremely short.
A kind of new high-temperature salt bath furnace body is done the burner hearth refractory brick marshalling with refractory brick.
Described refractory brick external body bag one deck fire-retardent fiber felt-rug.
Described fire-retardent fiber felt-rug is the aluminosilicate refractory fiber felt.
Described fire-retardent fiber felt-rug thickness is 10-30mm.
Described fire-retardent fiber felt-rug thickness is 20mm.
Described fire-retardent fiber felt-rug outside is welded with mild steel iron plate crucible again.
Described mild steel iron plate crucible thickness is 10-30mm.
Described mild steel iron plate crucible thickness is 20mm.
This new salt bath body of heater inside does not have the crucible of steel; refractory brick external body bag one deck aluminosilicate refractory fiber felt; outer one deck has the mild steel crucible of a thick 10mm again; like this in heat treatment heating process; after four jiaos of leakage salt of refractory brick marshalling, saline solution infiltrates refractory fibre and turns, and forms firmly protective layer of one deck; stop the leakage of fused salt, improved the life-span of body of heater more than one times.
