Wear-resisting steel ball tempering container with partition plates
ActiveCN110273058AImprove breathabilityImprove the tempering effectFurnace typesHeat treatment furnacesSteel ballEngineering
The invention discloses a wear-resisting steel ball tempering container with partition plates. The wear-resisting steel ball tempering container comprises a bottom frame. Multiple installing frames are uniformly installed at the top end of the bottom frame. An opening is formed in one end of each installing frame. One partition plate can be movably inserted to the outer side wall of one end, close to the opening, of each installing frame. Multiple air holes are formed in each partition plate at equal distance. Steel balls are arranged on each partition plate at equal distance. Multiple handrails matched with the steel balls are installed between the two adjacent installing frames at equal intervals. Each handrail comprises a telescopic rod mother rod and a telescopic rod son rod which are mutually connected. According to the container, a container body is composed of a bottom frame and multiple installing frames uniformly installed at the top end of the bottom frame, the adjacent installing frames are connected mutually through the handrails, air permeability of the container body is improved, thus the steel balls in the container body can be fully exposed in the air, the tempering effect of the steel balls in the container body is improved, and design is reasonable.

Valve base heat treatment device
InactiveCN109182668ASave energyEasy to placeFurnace typesHeat treatment furnacesMechanical engineeringHeat treated
The invention discloses a valve base heat treatment device which comprises a base. A first supporting plate and a second supporting plate are connected to the upper surface of the base symmetrically and fixedly. The ends, away from the base, of the first supporting plate and the second supporting plate are connected with a heating box with an opening formed in the upper end together. The heating box comprises an outer shell and an inner shell. A heat preserving layer is fixedly installed between the inner shell and the outer shell. A box cover is hinged to one end, away from the box bottom, ofthe inner wall of the inner shell. A heating device is installed on the vertical inner wall of the inner shell symmetrically and fixedly. The heating device is located below the box cover. The valvebase heat treatment device reduces consumption of resources effectively, moreover, the situation that the temperature of the device is lowered too fast can be prevented effectively, heat can be preserved effectively, and the tempering effect of a valve base is better.
