Description

Technical Field

[0001] The utility model relates to the technical field of sintering machine trolley guardrails, in particular to a sintering machine trolley guardrail with improved crack resistance and sealing performance. Background Art

[0002] The sintering machine is the main equipment in the sintering process, and the trolley is the basic equipment to ensure the smooth and efficient sintering process. Due to the alternating temperature difference between high temperature-low temperature-high temperature in the sintering process, the guardrail of the sintering machine trolley continuously expands and contracts during the temperature change, causing the guardrail to deform, or crack and gap. The guardrail is deformed and displaced, resulting in gaps between the trolley body and between two adjacent trolleys, resulting in increased air leakage rate, reduced output and utilization factor, and increased process energy consumption and cost.

[0003] In the prior art, the connections between the upper and lower guardrails and between the guardrail bodies are mostly fixed with bolts. As time goes by and the guardrails are displaced and expanded many times, the gaps between the guardrail bodies become larger, and the air leakage rate increases. In addition, the existing guardrails are severely worn by materials and wind speed, causing cracks and shortening their service life. After gaps appear between the guardrails and between the guardrail bodies, they cannot be effectively sealed, and the bolts may fall off after long-term use, thereby reducing the sealing performance.
