The lifting ring 6 can be convenient for hoisting equipment or placing measuring equipment at the bottom of a metal smelting furnace with a large volume. The connection between the hanging ring 6 and the hanging rod 4 can be welding or screwing.
The measuring device further comprises a base 3, wherein the bottom end of the suspension rod 4 is vertically arranged on the base 3, preferably, the bottom end of the suspension rod 4 is fixedly connected with the center of the base 3, and more preferably, the base 3 is circular. In order to facilitate reading and calculating of data, the boom scale 5 is arranged with the lower surface of the base 3 as a starting point.
The high-temperature metal melt refractory is a material of a high-temperature metal smelting furnace, in particular to a furnace bottom material. The high temperature metal may be any metal having a melting point of up to 500 c or higher.
When using measuring device, use hoisting equipment, for example the overhead traveling crane, utilize rings 6 to hoist measuring device, put into the stove perpendicularly from the top of high temperature metal smelting stove, can guarantee that jib 4 steadily places perpendicularly after device base 3 falls to stove bottom 1 bottom surface, read the scale on the measuring device in order to obtain from stove bottom 1 bottom surface to the stove outer covering along the shortest distance or the vertical distance between the horizontal plane that is located, the difference in height of the initial plane in stove bottom 1 bottom and the stove outer covering down along the horizontal plane that is located, stove outer covering height 7.
The high-temperature metal melting furnace includes a furnace bottom 1 and a furnace shell which is provided on the top end of the furnace bottom 1, that is, the lower edge of the furnace shell is joined to the upper edge of the furnace bottom 1.
The depth of erosion of the refractory material (i.e. refractory material of high-temperature metal melt) is the height measured (the height difference between the initial plane of the bottom of the furnace bottom and the horizontal plane of the lower edge of the furnace shell + the height of the furnace shell), wherein the height measured is the shortest distance or the vertical distance from the bottom surface of the furnace bottom to the horizontal plane of the upper edge of the furnace shell. The bottom initial plane of the furnace bottom means the bottom surface of the furnace bottom when the melting furnace is not in use. The bottom surface of the furnace used in the utility model is not specially described, which refers to the bottom surface of the furnace after the smelting furnace is used.
