A mounting groove 8 is provided on the inner side of the line brick 10, mounting blocks 11 are fixed at both ends of the inner liner 6, a fixing plate 12 is fixed above the inner liner 6, and pouring ports 13 are provided on both sides of the cladding 1, the permanent lining 2, the slag line brick 10 and the inner liner 6. A transmission mechanism 9 is provided on one side of the fixing plate 12, and a scraper 3 is connected to one end of the transmission mechanism 9 close to the inside of the inner liner 6. A mounting mechanism 7 is provided above the mounting block 11, and one side of the mounting mechanism 7 is connected to the slag line brick 10. The permanent lining 2 is a refractory fiber material, and the inner liner 6 is a high-alumina refractory material.

[0024] according to Figure 1-4As shown, the mounting mechanism 7 includes a reset spring 71, a rotating shaft 72, a limit pin 73, a positioning rod 74, a limit groove 75 and a threaded portion 76. The rotating shaft 72 is installed above the slag line brick 10 through a bearing. The outer side of the rotating shaft 72 is movably sleeved with the limit pin 73. The interior of the limit pin 73 is penetrated by a positioning rod 74. The outer side of the positioning rod 74 is sleeved with a reset spring 71. A limit groove 75 is provided on the side of the mounting block 11 close to the positioning rod 74.

The mounting block 11 and the mounting groove 8 are both in the shape of a "T".

[0025] During specific implementation, most composite masonry steel ladles do not have a separate inner liner 6. Due to long-term use, the inner wall of the composite masonry steel ladle will be worn, and the entire ladle needs to be replaced, reducing the practicality of the composite masonry steel ladle. The positioning rod 74 can be rotated to make the threaded portion 76 of the positioning rod 74 threadably engage with the limiting groove 75, so that the threaded portion 76 of the positioning rod 74 is disengaged from the limiting groove 75, and the positioning rod 74 is pulled upward and the reset spring 71 is squeezed, and then the limiting pin 73 is rotated by the rotating shaft 72 to make the positioning rod 74 deviate from the mounting block 11, and then the inner liner 6 is pulled upward to drive the mounting block 11 to disengage from the mounting groove 8, so that the inner liner 6 can be quickly removed from the composite masonry steel ladle for replacement, thereby improving the convenience of the composite masonry steel ladle.

[0026] according to Figure 1-2 and Figure 5-6 As shown, the transmission mechanism 9 includes a connecting rod 91, a gear 92, a rack 93 and a motor 94.

[0027] In specific implementation, when pouring, the ladle can be tilted at a certain angle through the rotatable support frame. Since the residual material is easy to adhere to the inner wall of the ladle, during the process of pouring the molten steel, the motor 94 can be started to drive the gear 92 to rotate, and then the gear 92 is engaged with the rack 93, driving the connecting rod 91 to slide to one side at the opening of the fixed plate 12, driving the scraper 3 to scrape to one side on the inner wall of the inner tank 6, scraping off the residual material, and assisting in pouring it out, which can reduce waste, facilitate cleaning work, and improve the practicality of the composite masonry ladle.

[0028] Working principle: When using this composite masonry ladle, first, the ear shaft 15 can be connected to the support frame. The composite masonry ladle is used to store molten steel. The composite lining composed of the cladding 1, the permanent lining 2, the cladding wall 4, and the slag line brick 10 can protect the ladle from metal corrosion and high-temperature corrosion. The air permeable plug 5 ensures the air permeability inside the ladle and improves the quality and purity of the molten steel. When the inner liner 6 is worn out after long-term use, the inner liner 6 is removed by the mounting mechanism 7. When pouring at the pouring port 13, the pouring can be assisted by the transmission mechanism 9 and the scraper 3. The scraper 3 can scrape off the residual material adhering to the inner wall of the inner liner 6, thereby improving the practicability of the composite masonry ladle.
