Problems solved by technology

However, these models either have no material tank system and cannot reflect the discharge behavior of the charge from the material tank, or the distribution method is simple and primitive, or only simulate the upper part of the furnace body and cannot reflect the overall drop behavior of the charge, or there is no air supply system, or the furnace body is a As a whole, it cannot fully reflect the distribution of the actual blast furnace charge level, and it also lacks the flexibility of experiments and measurements

Embodiment approach

[0027] The material tank system is made of the actual blast furnace material tank, which keeps the same shape and size and is reduced according to a certain ratio. The two material tanks 1 are welded together with the manual discharge valve 2 below to form a unit, and the two units are fixed by steel beams. The manual discharge valve is composed of a valve body and a valve plate. The valve body and the material tank are welded together. The valve body is a circular steel plate, and the steel plate is connected with a handle. The gate valve can be opened and closed by turning the handle. When charging, the person stands on the second-floor platform 15-1 and rotates the handle counterclockwise, so that the flapper valve is closed to block the bottom of the tank; when discharging, the handle is rotated clockwise, so that the bottom of the tank is in an open state. The material flow regulating valve 3 is fixed together with the second-layer platform 15-1 by bolts. It has two work...

Abstract

The invention discloses an experimental system for simulating bell-less parallel-hopper distribution of a blast furnace and belongs to the technical field of metallurgic experimental research. The experimental system comprises a hopper system, a distributor system, an experimental furnace body system, a reference furnace body system and an air supply system. The experimental system is highly similar to an actual bell-less distribution, has small experimental workload, is convenient and fast in measurement and observation, can reproduce the charge level distribution information in the radial direction of the blast furnace and the charge level segregation condition in the peripheral direction of the blast furnace according to the operation requirements of the blast under the condition that distribution matrix setting, hopper and material combination, the rotating direction of a chute and the air supply capacity are given, is suitable for studying the bell-less distribution rule of the blast furnace in a metallurgical laboratory, and plays a role in guiding the bell-less parallel-hopper distribution of the actual blast furnace.

Description

technical field [0001] The invention relates to an experimental system for simulating blast furnace bellless tank-merging and distributing materials, which belongs to the technical field of metallurgical experiment research. Background technique [0002] Blast furnace bellless and tank top is widely used in domestic large blast furnaces. The method of bellless distribution is flexible and diverse, and the tank combining system has compact equipment and high efficiency, which have been generally recognized by the blast furnace ironmaking industry. For the bellless tank merging system, the structure distribution of the radial layer and the segregation information in the circumferential direction are of great significance for the operators to operate the blast furnace. However, under normal blast furnace production conditions, the blast furnace is in a sealed state, and the operator cannot directly obtain the radial distribution of the material layer in the throat of the blast...
