Description
Technical Field
[0001] The utility model relates to the technical field of furnace mouth rib plate positioning, in particular to a device for positioning the furnace mouth rib plate. Background Art
[0002] A horizontal converter is a cylindrical rotary converting furnace with a central opening for charging, exhausting smoke, slag, and discharging. Horizontal vents are located on the sides of the furnace to allow air in. The entire converting process is an exothermic oxidation reaction, so the converter's conversion is driven by its own reaction heat. Due to large temperature fluctuations during the converting process, the intense erosion of the melt within the furnace, and the severe erosion of the furnace lining by slag and quartz flux, regular furnace maintenance is required. The kiln masonry includes three parts: the upper furnace mouth, the lower furnace mouth, and the eye bricks. The upper furnace mouth masonry process is more complicated. During the smelting process, the furnace mouth is often hit by the charge and washed by the molten liquid. Therefore, the furnace mouth area adopts wet masonry. The supporting arch should be lined close to the arch bottom, the contact surface must be tight, the arch foot surface must be flat, the angle must be correct, and the arch foot must not be leveled by thickening the brick joints. When building the supporting arch, the arch feet on both sides should be built symmetrically towards the center at the same time. The radial joints should coincide with the radial direction, and the inner surface should be flat. When closing the arch, a locking brick is driven into the center of the arch. When constructing the upper furnace mouth, the burned ribs need to be cut off first. After cutting, the new ribs need to be positioned and welded. Positioning requires repeated point-finding and line-measuring with tools such as rulers and angle squares. The operation is difficult and requires high precision. If there is any deviation, the fixed-size refractory bricks cannot be installed, resulting in rework. Therefore, the construction of the upper furnace mouth has problems such as long construction period and high rework rate. The long furnace repair time not only affects the production time of the furnace body, but also increases the workload and affects the company's benefits. To this end, we provide a device for positioning the furnace mouth ribs. Utility Model Content
