Product introduction of BBH box type multipurpose furnace

Equipment Overview: the introduction of BBH pre extraction box type multipurpose furnace has made the domestic heat treatment equipment leap to a new level. This series of furnace type organically integrates vacuum technology and controllable atmosphere, and has obvious advantages in environmental protection, energy saving and high efficiency.

Main applications: carburizing / carbonitriding / quenching under protective atmosphere, normalizing, annealing / secondary heating quenching.

Equipment features:

◆ there is no fire curtain at the front door, and the working environment is greatly improved.

◆ nitrogen replacement reduces the possibility of oxidation in grain boundary during heating and cooling.

◆ high safety performance, full automation and unmanned operation can be realized.

◆ high precision atmosphere control system can establish stable carbon potential in the furnace.

◆ when the furnace is shut down, the air will not enter the furnace, which saves the replacement time of the atmosphere in the furnace, and greatly shortens the time to establish the atmosphere during startup. Compared with the traditional multi-purpose furnace, the carbon potential establishment time is reduced and the operation cost is low.

◆ vacuum pumping is adopted in the front room, and there is no fire curtain at the front door, which saves a lot of fuel gas; The air tightness of the furnace is good, and the use of dropping agent is greatly reduced. Compared with the traditional multi-purpose furnace, the gas flow is reduced by 1 / 6-1 / 8.

◆ the vacuum feeding and discharging of the front chamber will not cause accidents due to the combustion of the fire curtain. At the same time, the oxidation and deterioration of the quenching oil will be reduced, the working environment is clean, the quality of the treated products is good, and the service life of the quenching oil has been prolonged. Quenching oil with all characteristics (including cold oil and hot oil) can be used.

◆ the equipment is equipped with residual oxygen analysis device in the loading room to ensure the safety of the equipment.

Performance comparison of bbh-3r & bbh-2r

◆ bbh-3r sets up an independent vacuum replacement chamber, which will not affect the normal use of the equipment during vacuum replacement, so as to improve the service efficiency of the equipment.

◆ the volume of bbh-3r vacuum chamber is reduced, so as to reduce nitrogen consumption and energy consumption.

◆ bbh-3r structure reduces quenching delay time compared with bbh-2r.

◆ bbh-2r / bbh-3r processing time comparison
