The author also made two bottom gas supply elements at the bottom d (radius) position along the trunnion direction of the ejector nozzle. The effect of the slag splashing in the double blow converter is still not as good as that of the top blow converter. In summary, the bottom blowing of the converter has a positive effect on the slag splashing protection of the double-blown converter, and the greater the flow rate of the bottom blowing gas, the more obvious. If the conditions permit, increasing the flow rate of the bottom blowing gas is beneficial to the slag splashing protection, especially for the upper and lower parts of the trunnion. It has been proved that the refractory material of the trunnion of the converter is no longer a weak link. The bottom blowing of the converter has an adverse effect on the slag splashing protection of the combined blowing converter. To ensure that the bottom gas supply component does not clog, the bottom blowing gas flow should be appropriately reduced when the slag is splashed.
Through testing and application, changing the slag composition, ie reducing or content, increasing the saturation or less supersaturation content, lowering the tapping temperature, and retaining the appropriate slag amount are all beneficial to improve the comprehensive level of slag splashing technology. The glycerin aqueous solution simulating slag provides the best slag splashing position of the top blowing converter on the spot, and the correction coefficient is the lower limit of the slag viscosity, which is the upper limit of the slag.
The top-blown converter adopts the angle of the nozzle hole and the oxygen lance to carry out the slag splashing operation. The steelmaking automation computer application closely related to the steelmaking production detects the refractory materials, environmental protection, energy saving and consumption reduction, comprehensive utilization equipment, improved production technology management, etc. There are fewer articles and fewer basic research articles. It is suggested that the content of these fields should be appropriately increased in the future to further improve the technical level of steelmaking production in China and the comprehensive level of related majors.
Honeycomb Blinds
Honeycomb Blinds also called Cellular Shades. window covering used to block or filter light and insulate windows to save energy. Cell size can vary. Cell shapes hold trapped air and create a barrier between the window surface and the a room. we have different fabric style provide to you choose, you can choose half light shading style, also can choose full light shading style Cellular Shades.
