The mixed type double-layer spiral reaction chamber comprises a first reaction chamber and a second reaction chamber which are sequentially arranged in the sample injection direction, and the first reaction chamber comprises a first double-layer spiral pipe composed of a first spiral pipe and a second spiral pipe which are arranged in a winding mode; the second reaction chamber comprises a second double-layer spiral pipe consisting of a third spiral pipe and a fourth spiral pipe which are wound with each other; the first spiral tube is detachably connected with the third spiral tube, and the second spiral tube is detachably connected with the fourth spiral tube, so that second channels for detecting the peroxide concentration in the sample are respectively formed. Different from an existing double-channel detector, the hybrid double-layer spiral reaction chamber provided by the invention has the advantages that the common part of the two channels is increased to the maximum extent through the double spiral channels, the sensitivity of equipment is improved, the use of parts and the volume and weight of the equipment are reduced, and the portability and the real-time detection sensitivity of the equipment are improved.

The present application relates to the technical field of part processing, and discloses a forging forming method and tool for large thin-wall drum-shaped parts, comprising the following steps: step 1, designing a forging drawing according to the size of the part; step 2, designing a tire mold tool according to the forging drawing; the tire mold tool comprises a hollow forming tire mold, an upper pad mold and a punching tool; step 3, determining the process parameters of staged heating and the forging process parameters of each step; step 4, performing forging forming processing according to the steps, and obtaining a forging part. The present application can achieve high product processing quality, help to improve processing efficiency and reduce processing cost.

The application discloses a diameter 1200-1700mm large-diameter seamless steel pipe sizing production method, and belongs to the technical field of seamless steel pipe manufacturing in the metallurgical industry. The application adopts large continuous casting billet piercing, cross rolling expanding, directly heating furnace reheating after equalizing cross rolling, on-line reheating, and then sizing, so that the production heating frequency of the steel pipe is reduced, the finished product inner and outer grinding and polishing are realized, the material yield is high, one roughing mill and one set of rolls can be used for sizing the large-diameter steel pipe, the outer diameter group distance of the sized pipe is large, that is, the roll commonality is strong, and the mold investment amount is reduced. The application utilizes the reciprocating rolling of the roughing mill and the movement and overturning of the push-pull bed, can balance the deformation of each surface, and the group distance of the two rolls for sizing the pipe is relatively large. Compared with the existing traditional steel pipe sizing and outer diameter control production process, the production frequency of the application is less, the production process is simple, the production efficiency is high, the mold investment amount is small, and the production cost is greatly reduced.
