[0023] The top of the hopper 9 is equipped with multiple lifting blocks 91, each with a hook hole 92. A support frame 93 is located below the side wall of the hopper 9. A discharge port is located at the bottom of the hopper 9, and a blocking plate 8 is installed at the discharge port. The side wall of the blocking plate 8 is connected to the support frame 93, and a support plate 81 is located on top of the blocking plate 8. A left connecting plate 2, a left positioning pin 3, a right baffle 4, a right connecting plate 5, a right positioning pin 6, and a positioning plate 7 are respectively located on the front and rear sides of the hopper 9. The left connecting plate 2 and the right connecting plate 5 are located on the left and right sides of the support frame 93. On the side, the outer ends of the left connecting plate 2 and the right connecting plate 5 are respectively connected to the support frame 93, and the left positioning pin 3 and the right positioning pin 6 are respectively connected to the inner ends of the left connecting plate 2 and the right connecting plate 5; the upper parts of the left baffle 1 and the right baffle 4 are respectively provided with left pin holes and right pin holes, which are respectively inserted into the left positioning pin 3 and the right positioning pin 6; the bottom of the left baffle 1 and the right baffle 4 is located above the blocking plate 8; the two positioning plates 7 are respectively located outside the left baffle 1 and the right baffle 4, and the support plate 81 is located outside the positioning plates 7.
[0024] The left connecting plate 2 and the right connecting plate 5 are positioned opposite each other and are at the same height; the left baffle 1 and the right baffle 4 are positioned opposite each other and are at the same height, located inside the left connecting plate 2 and the right connecting plate 5.
[0025] The support plate 81 is inclinedly connected to the top of the blocking plate 8. The blocking plate 8 is rectangular in shape and has baffles around its perimeter.
[0026] The upper part of the hopper 9 is rectangular, and the discharge port is also rectangular, with the inner diameter of the discharge port being smaller than the outer diameter of the hopper 9. Four lifting blocks 91 are provided on the top of the hopper 9, located at the four corners respectively.
[0027] The left baffle 1, right baffle 4, and positioning plate 7 are arranged obliquely. The hopper 9 is a bucket-shaped hopper, which is adapted to the shape of the lower part of the hopper 9. The inner wall of the discharge port is provided with cross-shaped partition plates 94.
[0028] The outer walls of the left connecting plate 2, right connecting plate 5, and positioning plate 7 are each equipped with reinforcing ribs. Their main function is to prevent the hopper body from deforming during the slag heating process, thus affecting the slag baking quality.

[0030] Working principle:
[0031] When smelting TP316H stainless steel in the electroslag workshop, the slag weight is 240kg. The granular slag is added to hopper 9 and the electroslag slag hopper device is pushed into the slag baking furnace by a pulley trolley for baking for 3-5 hours at a baking temperature of 750℃ and held for 4 hours. After baking, the slag is pushed out by a pulley trolley for air cooling.
[0032] After the slag material is cooled to below 100℃, the electroslag metallurgical slag hopper device is placed above the slag feeding trolley by suspending it through four hook holes 92 using steel wire ropes. When feeding the slag into the slag feeder, the positioning plate 7 on the outside of the hopper device must first be opened, the left baffle 1 and the right baffle 4 rotate, and the lower part separates to both sides. The slag feeding speed is controlled by controlling the separation width. The slag feeding time is ≤30s. Finally, the overhead crane hooks the hook holes 92 to smoothly feed the slag material from the hopper 9 into the slag feeder.
[0033] The terminology used in this invention is descriptive and exemplary, and not restrictive.
