Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for heating furnaces, and particularly relates to a mobile lifting device for a heating furnace. Background Technique

[0002] Continuous casting powder is an important auxiliary material in continuous casting production. In continuous casting production, it mainly plays the roles of preventing secondary oxidation of molten steel, heat insulation to reduce heat loss of molten steel, absorbing and dissolving non-metallic inclusions, lubricating between the mold wall and the billet shell, and improving and controlling heat transfer between the casting blank and the mold. Among them, the effect of continuous casting powder absorbing non-metallic inclusions has a great relationship with its own viscosity. In actual production, a heating furnace and a viscosity measuring instrument are often used to measure the viscosity of continuous casting powder. First, the continuous casting powder sample is heated to a molten state by the heating furnace, and then the viscosity of the continuous casting powder is measured by the viscosity measuring instrument.

[0003] Currently, the patent application number of the heating furnace developed by our company is 2021233782081, and the name is a heating furnace for a high-temperature viscosity measuring instrument. During the process of measuring the viscosity of continuous casting powder, it is necessary to cool down the lower part of the furnace shell of the heating furnace and the thermocouple at the bottom of the heating furnace through the lower cooling water device at the bottom of the heating furnace to ensure the smooth operation of the heating furnace. In the prior art, as mentioned in the patent application number 2021116470346, named a high-temperature viscosity measuring instrument for continuous casting powder developed by our company, the heating furnace is often directly placed on the base. For the convenience of staff operation, the height of the base is often relatively low, and it mainly plays the role of supporting the heating furnace. The following problems exist in actual application: 1. Every time the staff needs to repair and adjust the lower cooling water device at the bottom of the heating furnace, they need to move the heating furnace and place it on a higher support frame or place it on its side on the ground. Because the heating furnace itself is heavy, during the moving process, on the one hand, multiple staff members need to cooperate. If one person accidentally loses their grip, it may cause potential safety hazards. On the other hand, during the moving and placing process of the heating furnace, it may also cause bumps to the heating furnace, affecting the normal use of the heating furnace; 2. Because the height of the base is fixed, the height of the heating furnace cannot be conveniently and quickly adjusted according to actual needs; 3. In actual use, there will be situations where the heating furnace needs to be moved. The base in the prior art cannot be moved and can only be carried by the staff, which is time-consuming and laborious. Moreover, the base cannot support the heating furnace to remain stable on uneven ground, which will cause the heating furnace to shake and affect the viscosity measurement result.
