When does the glass furnace need to be cold repaired?Ⅱ--Preparation works before cold repair
a. Design and material preparation Before the cold repair, according to the new kiln production plan and the experience of the old kiln, the need for cold repair parts and technical transformation plan, and then the theoretical calculation and structural design, and the materials required for cold repair according to the structural design plan.
b. The materials used for masonry preparation (mainly refractory materials) should be carefully inspected after they arrive at the factory. The bricks to be processed should be ground and cut, and special parts should be pre-built.
c. Plan to schedule the schedule of the project before the cold repair, so that the specific construction personnel can clearly define the operation method and quality requirements, and do a good job in the staffing and training.
D. Review the drawings and draw all the drawings in detail before drawing the line, and find the errors and correct them immediately. Before the construction, the location of the masonry should be determined on the site according to the drawings and the line should be drawn. The most important line is to determine the center line, the drip center and the liquid level.
e. In order to ensure the accurate size of the masonry in standard line and model masonry, there must be standard lines or samples. The standard line is generally marked with a string to indicate the vertical and horizontal lines of each part, and the sample is measured by the standard shape of steel or wood. Before the building, you should pull the standard line and make a good model.
f. Prepare tools for masonry such as bricklaying, brick cutting, and concrete.
The release of the molten glass from the furnace is an important part of the cold repair work. The requirements for the discharge work are safe and thorough. At present, there are two methods for discharging float glass furnaces: one is to discharge the material by using a glass discharge tank; the other is to release water by water quenching. Taking the glass discharge tank as an example, the work preparation and operation steps of the discharge are described below.
