The shell of the hydraulic tilting trolley is welded with steel plate and section steel. The bottom of the furnace body is connected with the light rail of the trolley. The user does not need to install the foundation. It can be used only by placing it on the flat cement ground. The lining uses ultra-light refractory bricks as lining, which saves about 80% energy compared with traditional brick hearth. The lining uses high-quality long fiber blankets, diatomite bricks and vermiculite powder as insulation materials. The hearth adopts heavy anti-collision bricks and high-alumina anti-pressure bricks on the surface of trolley. In addition to the labyrinth refractory between the furnace body and the trolley, the self-acting sealing mechanism is used to reduce the heat radiation and convection loss of the furnace, and to improve the furnace temperature uniformity. The heating element is made of high temperature resistance alloy wire wound into spiral shape, which is distributed on the furnace side, furnace door, back wall and placing trolley shelf brick. It is fixed with the national standard socket brick, which is safe and simple.

　　The trolley is equipped with a pressure-resistant and high temperature-resistant bottom plate of the steel casting furnace for carrying the workpiece. In order to prevent the oxide scales produced by workpiece heating from falling into the heating element through the gap between the bottom plates of the hydraulic tilting trolley furnace and causing damage to the heating element, the insertion contact is adopted between the bottom plates of the furnace and the furnace body. In order to ensure normal use, it is necessary to clean the oxide skin under the bottom plate of the trolley hearth regularly, usually once a week. When blowing, the bottom plate of the hearth is lifted, and the oxide debris in the resistance groove is cleaned by compressed air. Attention should be paid to preventing short circuit caused by the oxide pickup in the hearth.
