Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] The invention provides an ammonia cracking furnace, which replaces the traditional heat-resistant brick furnace lining with a vacuum-formed ceramic fiber module, and embeds the heating wire into the ceramic fiber module, and adds explosion-proof to the exhaust pipeline of the ammonia cracking furnace. cover as well as pressure switch and normally open pneumatic angle seat valve to ensure the safety of the ammonia cracking furnace. The ammonia cracking furnace of the present invention is light in size, can be directly placed on the casing of the pre-vacuum nitriding furnace, can save ground space, and has the characteristics of simple structure, convenient operation, high control precision, safety and reliability. The ammonia cracking furnace of the present invention will be described below in conjunction with the accompanying drawings. ...

The invention relates to an ammonia cracker, characterized by comprising: a housing having a receiving space for vacuum welding; a reaction tank disposed in the receiving space of the housing and fixedly connected with the housing; an intake line communicated with the reaction tank and used for introducing a reaction gas into the reaction tank; an exhaust line disposed at the top of the reaction tank and which extends into the reaction tank, with an intake port of the exhaust line positioned at the bottom of the reaction tank and used for exhausting a gas generated in the reaction tank; a heating module disposed in the receiving space of the housing and which sleeves the reaction tank and is used for heating the reaction tank, with the heating module including a ceramic fiber module and a heating wire cast and fixed in the ceramic fiber module, wherein the heating wire is close to the reaction tank and partially exposed from the ceramic fiber module. The ammonia cracker is simple in structure, convenient to assemble, cost-saving, and secure and reliable.
Description
technical field [0001] The invention relates to the field of nitriding, in particular to an ammonia cracking furnace. Background technique [0002] Nitriding is a surface hardening process that adds wear resistance, impact strength and corrosion resistance to the workpiece surface. Although the craft has been around since the dawn of this century, it is rarely understood. In particular, unlike carburizing, the control of nitriding process is more complicated, and it is difficult to obtain products with good repeatability and high precision by traditional control methods. Only recently has it attracted attention due to the development of precise control of the nitriding process. [0003] At present, the ammonia cracking device configured in the pre-vacuum nitriding furnace production line is basically placed on the ground, and its furnace lining is made of heat-resistant bricks, resulting in a relatively heavy weight and a relatively large floor area. . The heating wire i...
