Abstract

The present invention relates to improvement of structure of homogeneous furnace capable of carrying out anti explosive treatment on toughened glass. The invention provides a homogeneous furnace for toughened glass which is energy-saving and highly production efficient. The homogeneous furnace comprises a furnace body, a furnace door and an air cooler being installed on both sides of the furnace body respectively. The structure of the furnace is characterized in that a temperature-insulating layer is installed on the periphery of the furnace body, thermal cycle ducts are installed at the two sides of the furnace body and at the temperature-insulating layer on the top, a heater and a circulating fan are installed at the bottom and the top of the thermal cycle duct respectively, and a cooling cycle duct is installed between the thermal cycle ducts on the top of the furnace body.

Description

Technical field: [0001] The invention relates to the structural improvement of a homogeneous furnace for anti-self-explosion treatment of tempered glass. Background technique: [0002] The equipment of the present invention is a special equipment for anti-self-explosion treatment of tempered glass; the tempered glass will still self-explode under the condition of no external force. The reason is that nickel sulfide is in a high temperature state (α-Nis) during the heating stage of tempering treatment. In the rapid cooling stage of tempering, the high-temperature state (α-Nis) has no time to transform to the low-temperature state (β-Nis). This crystalline transition persists from minutes after processing to more than a decade after installation. The transformation of (α-Nis) into (β-Nis) will cause volume expansion, break the stress balance inside the glass, and cause the tempered glass to self-explode. To make the treated tempered glass no longer self-explode. The temper...
