求翻译：当产品经过高火保温阶段后，关闭燃气总阀及支阀，可由助燃风机通过助燃风支管向窑内打入急冷风，使产品按曲线冷却。是什么意思？

Combustion fan after high fire insulation stage, close the gas valve and the branch valve by acute cold air through the combustion air manifold into the kiln to make our products the curve cooling.

When the product is high-fire warm phase, close the gas valve and the valve, and can be caused by combustion turbine combustion through the support tube to the kiln into a cool, cool products as curve.

After the product passes through the high fire heat preservation stage, the shutting down fuel gas main valve distributing valve and a valve, may by aid combust the air blower to infiltrate the anxious cold wind through the combustion wind branch to the kiln in, causes the product according to curve

When the product is a high fire insulation stage, turn off the gas valve and valve-General, by the combustion-supporting blower by emergency teams in the combustion air pipe to the kiln cool air, causes the product curve cooling.
