求翻译：除进坯和出坯由于进出窑需要而设置窑门，窑侧设有观察孔、检测孔外，没有任何孔洞，封闭严密，减少了窑体热量散失。是什么意思？

Addition into the billet and the billet kiln door set due to the need out of the kiln, the kiln side has observed hole detecting holes, no holes, closed tightly, reduce the heat loss of the kiln.

In addition to raw and unprocessed in the kiln and kiln door need to be set up, and the kiln side holes, test holes, there are no holes, closed tightly, and reduce heat dissipation in the kiln.

Except that enters the semifinished product and the semifinished product needs to establish the kiln gate as a result of the turnover kiln, the kiln side is equipped with outside the port hole, the examination hole, did not have any hole, the seal to be strict, reduced kiln volumetric heat quantity
