Iron ore high-temperature performance measuring device

Abstract

The invention discloses an iron ore high-temperature performance measuring device, and the device comprises a frame mechanism, a lifting mechanism, a heating furnace mechanism, a chassis mechanism, agas distribution mechanism and a loading mechanism; the frame mechanism comprises a horizontal base and a vertical supporting frame installed at one end of the horizontal base; the lifting mechanism is arranged on the vertical supporting frame and can ascend and descend along the vertical supporting frame, and the heating furnace mechanism is fixedly connected with the lifting mechanism. A crucible is arranged on the chassis mechanism, and the chassis mechanism is arranged on the horizontal base and can move to the position below the heating furnace mechanism along the horizontal base; an airinlet pipe of the air distribution mechanism is communicated with an inner cavity of the chassis mechanism, and the loading mechanism extends into the heating furnace mechanism from the upper part toapply pressure to a sample in the crucible. The determination device can be used for taking and placing the crucible more safely, quickly and conveniently, so the detection of the high-temperature performance of the iron ore is safer, lower in consumption, quicker and more accurate.

Description

technical field [0001] The invention belongs to the technical field of iron ore high-temperature performance detection, and relates to an iron ore high-temperature performance measurement device. Background technique [0002] At present, the high-temperature performance testing equipment used for iron ore (lump ore, sinter, pellet ore) as raw material for ironmaking is mainly divided into two categories. [0003] The first is the fixed furnace body type, the heating furnace body does not move, and the crucible and indenter for testing need to be inserted and lifted from the top of the furnace body with a clamp, which requires a certain amount of physical strength to complete. The operation is cumbersome, heavy and unsafe. [0004] The second type is the liftable furnace body type, the heating furnace body can move up and down, the furnace body rises and then rotates to the side to facilitate the loading and unloading of the crucible, the crucible and indenter for testing ca...

AI Technical Summary

Problems solved by technology

[0005] These two iron ore high-temperature performance testing equipment do not have a micro-positive pressure nitrogen protection system, and there is a problem that the carbon base and the pressure rod are easily oxidized and damaged.

[0006] The first type of equipment also has the problem that the crucible for testing the test material needs to be hoisted from the top manually and installed with a load. In particular, it is necessary to lift the high-temperature crucible out of the furnace, which is not only cumbersome to operate, but also takes a long time and is extremely unsafe.

It cannot meet the requirements of safe, low consumption, fast and accurate metallurgical performance inspection for iron ore raw materials in ironmaking

Even the second type of equipment still has the problem that the furnace body is raised and then turned to the side, which is easy to damage the heat-dissipating element.
